Abstract

Objective: To evaluate the results of concomitant maze and prosthetics of the ascending aorta with a valve-containing conduit.

Methods: From 2013 to 2017, six patients with AF and pathology of the ascending aorta were operated on. The maze procedure was performed in conjunction with the prosthetics of the ascending aorta with a valvular conduit. The average age of patients was 53 ± 14 years; (5 men), EF 46 ± 10,8%. The duration of AF before the operation was 44.2 ± 38.2 months. 3 patients had persistent, 3 - permanent form of AF. 5 patients had an aneurysm of the ascending aorta, 1 - chronic dissection. In 2 patients a Marfan syndrome had been diagnosed. All interventions were carried out in a planned manner. Concomitant procedures: correction of mitral, tricuspid insufficiency and in one patient CABG. The mean follow-up period was 14.3 ± 10.6 months. ECG, Holter monitoring data, ECHO-CG, need for repeated RFA interventions, pacemaker implantation, SF-36 questionnaire were evaluated.

Results: In-hospital mortality was 0%. Bypass time was 162 ± 26.4 min, ischemic time - 133 ± 28.3 min. At the end of hospital stage we had a restoration of sinus rhythm in 100% of cases. One patient had a paroxysm of AF which had been treated with amiodarone. During follow-up period all patients retain a sinus rhythm.

Conclusion: The implementation of the maze procedure shows good efficiency. Despite extensive surgical intervention and a longer period of myocardial ischemia, satisfactory results for survival and recovery of sinus rhythm are shown.
